As Mashable notes, a Twitter hoax claiming the pop icon was diagnosed with cancer swept through the Internet this week, giving Beliebers everywhere a collective heart attack.

The hoax reportedly started on Oct. 22 with a screenshot of what appeared to be a tweet from Entertainment Tonight's official Twitter account, the tech website writes. The fake tweet announced that Bieber had been "diagnosed with cancer" and "suggested that fans go #BaldforBieber" in support of the pop sensation.
